HS-RN MP-2100/2104 Ver. 12.6, MP-4100 Ver. 2.0 Overview 1-1
Chapter 1
Introduction
1.1 Overview
This manual describes the technical characteristics, applications, installation and
operation of the HS-RN four-channel low-speed data modules for use in
Megaplex-2100, Megaplex-2104, and Megaplex-4100 integrated access
multiplexers.
HS-RN modules provide functionality similar to that offered by the HS-R modules
long available from RAD, but use improved hardware that can utilize all the four
TDM buses in the chassis (a capability supported only by Megaplex units equipped
with CL.2 modules and running software version 11.0 and higher).
Product Options
Two module versions are offered:
• HS-RN: a proprietary HDLC-protocol based module version featuring
Bandwidth and Latency optimization.
• HS-RN/V.110: a special version for operation in the V.110 mode, fully
compatible with the old HS-R module.
In this manual, the following generic terms are used:
• The term HS-RN is used when the information is applicable to both the HS-RN
and HS-RN/V.110 modules.
• The term Megaplex is used when the information is applicable to all the three
Megaplex chassis.
The complete designation is used only for information applicable to a specific
equipment version.
Main Features
The HS-RN modules provide four independent V.24/RS-232 channels with DCE
interfaces that support full duplex asynchronous and synchronous data
transmission in the range of 0.6 through 64 kbps. The supported data rates
depend on the HS-RN model and encapsulation method (see
Table 1-1 ).
Each channel has local support of RS-232 control signals. Alternately, each
channel can be configured to transmit RS-232 control signals end-to-end (this is
possible at all the rates, except for 56 and 64 kbps):
